i RADIATOR.

Application filed; May 17, 1923*. Serial No. 639,552.

To all whom t may concern:

Be it known that we, CLiN'roN H. WENT- won'rrr and LLOYD H. XVALLNER, both citi- Zens of the United States, residing at Los Angeles, in the county of Les Angeles and State of California, have invented a new and useful Radiator, of which the following is a specification.

This invention relates to radiators and is particularly directed to that general typo of radiator adapted for use as a unit of the water' cooling system of a motor vehicle.

It is an object of this invention to pro.- vide a radiator having a removable core unit capable of being removed from or in'- serted in the radiator framework through the front opening therein, whereby a replacement of the core may be accomplished without bodily removing the entire radiator from the machine.

lt is a further object to provide a radiator structure of this nature in which they requirement for an outer finish shell is obviated, and in which the manifolds for-m a part of the finished framework of the radiator.

Another object is to provide a radiator having a contour flange definingthe shape of the upper portion of the front opening in the radiator framework, and having-a core unit adapted to be inserted or removed through said front opening by first having its upper end inserted beneath said contour flange and its lower end then'moved rearwards to place. Y A

Various other objects and advantages will be more fully apparent from the following description of the accompanyingl drawing, which forms a part of this disclosure, and o which illustrates a preferred forni of enibodiinent of the invention. I

Of the drawings:

Fig. l is a front elevation of a radiator' Vconstructed in accordance with the present invention,

Fig. 2 is a top plan view. Fig. 3 kis a plan section on line 3-3 of Fig. l.

Fig. t is a plan sect-ion on line lf-.d of Fig. l.

Fig. 5 is a central vertical section.

Fig. 6 is a front elevation of one of the interchangeable core sections.

Fig. Z is anl enlarged plan view of one of the end castings of a core section.

In the drawings is illustrated an autemobile radiator in which the upper manifold A and the lowermanifold B, are sep.i

arate castings and are joined together by side members C to form a coin-plete framework` adapted to. receive the. detachable core, indicated generally by the reference character D. l

lt is usual in radiator construction, to first construct the manifolds and core and to then place such completed structure within a shell of sheet metal, the shell bein g of the desired contour and finish t0. harmonize with the general design and finish of the automobile. rlhe front wall of the usual radiatorshell is of more orless ornamental contour and to a certain degree overlaps the front side of the radiator core, mal:- ing it impossible to. remove the core through the front opening in the shell, even in instances where a rremovable core isprovided. It will be evident that in a vradiator having avremovable core which can only be removed from the rear side, such removal cannot be accomplished without first bodilyfremoving the` entire radiator from the machine, due

to the fact that in ordinary automobile construction the engine -is positioned too close to the radiator to otherwise permit; a removal of the radiator core,

Fur-ther, in contemplating Vthe removal and linsertion of a core through the front opening of the shell of a radiator, it will be evident that unless special provisions are made, the front opening would have to be of the same shape and size as the core. This would necessitate a separate sine and shape of core for every site and design of radiator. It is a purpose of the present invention to provide a radiator' which does not require a shell and which has a core unit capable of being removed and replaced by another similar unit, 'without removing the radiator from the machine 1 To this end lle upper manifold ri has an exterior contour conforming to the 'desired finished contour of the upper portion of the radiator and has opposite limbs l() to which thev channel side members B are secured preferably by bolts l1, the lower ends of the members B embracing and being secured to the lower mai'iifold C by bolts 12. This provides a substantial rigid framework having a finished exterior surface, it of course being understood that the upper manifold A may be of other exterior shape than the rounded form shown.

The upper manifold A has the usual lilling opening 13, an inlet port 14C and a relatively short baffle web 15 just above the inlet port. The lower rear wall 16 has, in this instance, three ports 17 which are adapted to register with the inlet openings of the core.

The lower manifold C has an outlet port 18 (see Fig. 4) and its front wall 19 has three ports 2O which are adapted to register with the lower outlet opening of the core.

In the present instance it is preferable to form the core D of a plurality of separate sections 21, there being three of such sections shown. These core sections are of uniform construction and are therefore interchangeable one with another. Each comprises opposed vertical side plates 22 and an intermediate honey-comb structure providing a plurality of more or less vertical water channels and intermediate horizont-al air spaces, this intermediate core structure as shown being only for the purpose of illustration as it is evident that any of a large number of specific core constructions may be utilized. Secured to the opposite ends of each core section 21, preferably by soldering, are terminal castings 23 and 24 which are of duplicate form but which are reversed as to relative position.

Each casting 23 provides a. shallow chamber 23"L of sufficient size to communicate with the upper ends of all of the water channels of the respective core structure, and has an upwardly extending inlet branch 23b terminating with a vertically disposed flange 23C adapting it to be attached to the rear wall 16 of the upper manifold A by bolts 25, and with its inlet branch 23b in registry with the respective port 17 (see Figs. 3 and 5). Each casting 24 likewise pro-vides a shallow chamber 24 communicating with the lower ends of all of said water channels and has a downwardly extending outlet branch 249 erminating with a vertically disposed flange 2te adapting it to be attached to the front wall 19 of the lower manifold C by bolts 26, and with its outlet branch 24h in registery with the respective port A20, (see Figs. 4C and It will of course be understood that between the several flanges 23 and 2 C and the manifolds there will be provided suitable gaskets to insure water tight joints.

With this structure the 'bolts 25 which secure the core units or sections 21 to the upper manifold A are easily accessible from the rear side of the radiator, while the bolts 26 which secure said sections to the lower manifold C are easily accessible from the front side of the radiator.

lVlien it is desired to remove a corc section the bolts 25 and 26 of said section are removed and the lower end of the section is then pulled forward, as indicated in dotted lilies in Fig. 5, after which the section will easily drop out, a replacement of a section being accomplished in a reverse manner.v

This construction permits the upper manifold A to be provided with a contour flangej 28 overlapping the upper ends and outer corners of the core D, and which may be of any desired shape without in any way interfering with the replacement of the core sections.

From the above it will be evident that we have provided a. radiator in which the framework comprising the manifolds and side members present a finished appearance without requiring an outer shell, and in which the core may be removed through the front opening` of the radiator so as to render it convenient and easy to replace a worn out core with a new core without rst removing the entire radiator from the machine, the core sections being so formed as to be bolted at their upper ends to a rear vertical wall of the upper manifold and at their lower ends to a front vertical wall of the lower manifold.

-While the form of construction herein illustrated and describe-d is fully adapted to fulfill all of the objects primarily stated, it is to be understood that we do not wish to limit the invention in this regard, for it is susceptible of embodiment in various other forms, all coming within the scope of the following claims.
